TOOL FOR FORMINGBOTTLE-NECKS.

SPECIFICATION forming part 0f Letters Patent NO. 646,848, dated April 3, 1900. Application filed January 21, 1899.l Serial No. 702,965. (No model.)

scription of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to tools for forming bottle-necks and the like; and it has for its object to increase the capacities and efficiencyy of such tools. Y

The invention consists in the construction herein described and pointed out.

In the accompanying drawings, Figure 1 is a perspective View of the tool. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 isa section on line 8 3 of Fig. 2. Fig. 4 is a longitudinalsection of a tool embodying modified details. Fig. 5 is a plan of a sectional mold and its casing, showing the moldsections expanded. Fig. 6 is a perspective of one member of an expander. Fig. 7 is a perspective of the parts of the ball-housing shown separated.

Referring to the drawings, 1 denotes a spring-bow adjustably held vupon a rod` 2 by nuts 3.

4 denotes a casing for the bottleneck mold.l

. The lower end of this casing is movably supported upon a tube 9, secured to the upper end of rod 2, asby screws 9. Said casing is enlarged or flared at its upper end, as at 5, for a purpose hereinafter described. Y

6 indicates a neck-mold comprising two longitudinal sections having cooperating semicircular ledges 7, constituting the bottom of the mold. The mold is mediately supported by the bow and the necessary intermediate cooperating devices. l

6 indicates partial coperating screwthreads in each mold-section adapted in op- -eration to produce screw-threads on the bottle-neck.

Although screw-threads are shown and described herein, it must be understood that the forming of grooves, indentations, or the like are within the capacity of the tool, suitably modified for the purpose, and that such modifications and othersknown to skilled mechanics are within the scope of the invention and claims.

The mold-sections are loosely connected by parallel pins 10, arranged at right angles to the moldsywhereby said sectionsare guided and permitted to moveto and from each other in lines parallel to said plane.

11 denotes lugs fixed to the mold-sections and provided with slots 12, adapted to receive the edges 13 of notches formedv in the ared end 5 of the casing, the construction being such that an endwise movement of the casing produces a transverse movement of the moldsections in parallel lines.

The casing is moved by compressing the bow, which loosely engages the fingers 14, mediately connected to the casing, supported to slide lengthwise the tool. As the bow is compressed the casing is pushed forward by means of the forwardly-inclined parts of fingers 14 and its flared end pushed through the lugs 11,v with the effect to close the V'sections in mannerto make the partial screw-threads and partial ledges continuous and coperative with their fellows.

The tube 9, fixed to rod. 2 by pins 9', as stated, has a fiange 9" contiguous the/moldvbottom consisting of the ledges 7. The flange 9 stops the backward movement of the mold lengthwise the tool. l The mold is further fixed against lengthwise movement by pins 15, which enter sockets in the housing-ring 16. The mold-bottom is held adjacent the flange 9 in manner to avoid friction when the mold [is rotated; lbut the play between the flangev yand mold-bottom is preferably very small in order that the flange may promptly stop the mold and partially relieve the pins 15 when the. casing 4 is retracted by t-he expanding bow. v

17 denotes a plug xed in the tube 9. Its free end is suitably formed to enterthe mouth of a reheated bottle-neck.

' An expanding throat-former comprises two members 18, each having a groove 19 to em` brace a pivot 20, and they are held in engagement therewith by tube 9, as shown. Said pivot is supported in tube`9. Theouter ends of the members of the throat-expanding former are situated in a slot in the plug 17 IOO and can be moved about the pivot 20, with the effect to move their outer ends in and out of said slot, as required to expand and form the bottle-throat-that is, the interior of its neckand force the glass into the screwthreads or like indentations. This movement of the throat-former is effected by the bow immediately after it has closed the mold-sections and by an additional compression of the bow, which causes its limbs to engage the transversely-movable pins 21, connected to the inner ends of the expander members 18, with the effect to close said inner ends and open their opposite ends, as above noted.

22 indicates returning-springs.

14 denotes portions of the casing-moving fingers, which portions are arranged at right angles to the axis of the tool to avoid moving the casing lengthwise during the operation of opening and closing the expander, and it is to be understood that the bow members are contiguous these portions 14/ during the throat-forming operation.

In Fig. 4 is shown a modiiication adapted to positively move the expander members in both directions. The pins 21' pass through the bow members, and each is provided with collars or heads 21", one on each side of a bow member, whereby whether the bow is being opened or closed the expander members are positively moved at suitable times.

As shown in Fig. 4, the expander can be applied to a tool having a circumferentiallyintegral n eck-mold and transVersely-movable sections 6X, which latter construction forms no part of the present improvement.

Referring again to the ball-bearing comprising the housing-ring 16, said ring has two exterior bearing-faces 24 and 25 cooperating with oppositely-situated faces 24 and 25, formed, respectively, on a sleeve 24 and a cone 25, secured on said sleeve. This device facilitates the rotation of the mold about the plug 17 and tube 9. 27. denotes a similar housing-ring for antifriction-balls, situated between the mold-casing 4 and the tube 9. The other parts of the housing are formed and arranged as shown and are similar to those described in connection with ring 16.

Either housing is such that the tool can be taken apart for cleaning or other purposes without releasingthe balls, and, if desired, the entire housings can be detached without freeing the balls.

The lower housing just referred to comprises a ring 27 and a cone 29 and sleeve 26.

2S denotes screws, securing together the mold-casing 4 and ring 27.

In operation, the bottle being removed from the glory-hole of the reheating-furnace by means of the snap, its semifluid neck is pressed upon the plug and into the mold, which, being closed on the neck, forms screwthreads or other indentations thereon and also the bottle-lip, which is perfected by the rotation of the bottle and mold upon the fixed moldbottom.

Having thus described myinvention, what I claim is 1. In a tool for forming bottle-necks, the neck-mold sections adapted to form the neck, means for guiding them to and from each other in right lines, a spring-bow, and devices intermediate the bow and sections to open and close said sections by the bow.

2. In a tool for forming bottle-necks, the neck-mold sections having dies fixed thereto to form screw-threads or the like, means for guiding them to and from each other in right lines, a spring-bow, and devices intermediate the bow and sections to open and close said sections by the bow, said devices comprising a casing operatively connected with each section and moved by the bow.

3. In a tool for forming bottlenecks, the neck-.mold sections adapted to form the neck, said sections being loosely connected by parallel pins, means for guiding them to and from each other in right lines, a vspring-bow and devices intermediate the bow and sections whereby they are opened and closed by said bow.

, 4. In a tool for forming bottle-necks, a neck-mold, a throat-expander to form the neck interior comprising pivoted members and a bow operatively connected to the ex pander members, said connection comprising pins situated in the path of the bow members and connected to and carried by the expander members whereby said members are directly opened.

5.
